4 Claims. 1

This invention relates generally to shaker conveyors and more particularly to an improved form of swivel connection for shaker conveyor trough line.

Heretofore in shaker conveyor trough systems having a swivel frame at the inby end cooperating with a loading device for gathering material from all parts of a mine room or the like, the trough sections at the swivel frame and base have been nested in each other with arcuate sides and pin connections so that the pivoting trough sections are capable of taking the stresses incident to the shaking motion of the trough conveyor According to the present invention the swivel trough at the inby end of the swivelconnection is caused to discharge its contents onto the outby trough of the swivel connection. The outby trough is ared so as to accommodate the discharge of the inby trough for all swiveling positions thereof, and is additionally provided with spring steel sides which are deformed in movement of the swivel trough so that it may discharge its contents well away from the inby end thereof. In carrying out the invention the swivel trough is supported on a swivel frame pivoted to a base supporting the inby end of the outby shaker trough, and a drive linkconnection is afforded between the two troughs, and so arranged that motion may be transmitted between the two troughs irrespective of varying contours of the ground upon whichthe troughing is supported. As an adjunct to the invention a simple means is afforded for centering the base supporting the swivel connectionvpriorv to holding the base in position by jacks bearing against a mine roof or the like.

With the foregoing considerations in mind, it is a principal object of this invention to provide an improved form of swivel-trough. connectionfor shaker conveyors characterized by extreme simplicity and reduced weight. Y

Another object is to afford a swivel-trough connection characterized particularly by troughing which is not required to be nested one in another in eifecting the swivel connection.

Still another object comprehends the provision of a simple linkage extending across the point of articulation of the trough sections and constructed in such a fashion as not to interfere with the movement of material on the trough sections and so as to transmit motion between the trough sections eiciently y Other objects and important features of the invention-wil1 beapparent from a study of-'the following specification taken with the drawings which together illustrate a preferred embodiment of the invention and What is now considered to be the best mode of practicing the principles thereof. Other embodiments of the invention will be apparent to those` having the benefits of the teachings herein, and it is therefore intended that the invention not be limited by the precise embodiment herein shown but only by the scope and terms of the appended claims.

In the drawings:

Figure 1 is a plan View of a swivel trough connection for -a shaker conveyor having embodied therein the improvements according to the kpresent invention; i r

Fig. 2 is a side view thereof partsbeing 4broken away to show certain details of construction;

Fig. 3 is an enlarged transverse section taken along the line 3 3 of Fig. 1 looking in the direction of the arrows, and showing details of the pivotal connection of the swivel frame with the base; f

Fig. 4 is a section taken along the line 4-4 of Fig. l looking in the direction of the arrows, showing the swivel trough connection base held in position by roof jacks; and

Fig. 5 is a perspective View of the swivel connection base together with the swivel frame and the swivel trough reciprocating support.

Referring now to the drawings, the improved swivel trough connection is indicated generally by the reference numeral ID and includes a ibase plate II overlying a pair of laterally spaced jack pads I2 and i3, pad I2 being shown with a recess I4 for a roof jack I6, the pad I3 having a similar recess Id for a roof jack Il, the two jacks vIE5 and Il holding their respective pads in position. As has been stated,rthe base'plate II overlies the jack pads I2 and I3, and springs I 3 encircling studs I9 passing through the base plate II, and held between the base plate lII and stud nuts 2l, are arranged to provide movement of the jack pads I2 and IS with respect to the base plate II to accommodate irregularities in the mine floor.

An outby trough 22 is bolted at 23 to a flared trough section 213 supported on a Y-shaped frame 25 having laterally extendingarms 2l, 2l each terminating in a clevis 2S to receive a beveled rol-ler 29 which travels with the frame 26 and the trough sections 22 andf24 in laterally spaced V-rails 3|, 3l, each supported-0n spaced vertical standards 32, 32 secured to the base plate Il.

In Fig. 5 the bevel rollers 29 are shown disengaged from the V-rails-SI- for the purpose of clarity, but the rollers 29Uare designedy to ride Vfor a purpose as will appear.

in the rails 3| on reciprocating movement of the shaker trough sections 22 and 24. In order that the base I I supporting the rails 3| may be properly centered prior to placing of the jacks I6 and I1, the frame 26 is arranged with depending stops or abutments 33 and 34 which engage centering members 36 disposed on eali side of centering blocks 31 laterally 'disposed on top of the base plate II, and extending laterally under the V- rails 3|. Each centering member 36 is provided with a, slot 38 cooperating Withstub pinshSS', see Fig. 4, extending from the supports 32 andV ward each other to guide the centering members 36. A handle 4| is connected toA the centering members 36 and enables to b e pulled 'out-f wardly together from the dotted line position arid then to be rocked on the pins 39 to the position seen in Fig. 4. The operation just describedris performed during a few initial strokes of the conveyor, which centers the blocks 31 and the base plate I I, the centering members being then rocked `as described to m'ake way for the roof jacks I6 and I1.

An inby trough- 42 is mounted on a reciprocating trough support 43 which is guided within and supported upon a swivel frame 44 arranged to swivel with respect to the base plate I. The inby swivel trough "42 is arranged so that its outby end overlies the' flared trough section 24 to discharge its contents thereon. In vorder to accommodate the swiveling movement of the -inby trough 42, the 'in-by end of the flared trough section 24 provided with spring steel sides 46 which deform as seen i'n'- Fig. l during the swiveled position shown of the inby trough 42.

The swivel frame 44 is arranged to turn on a pedestal 41, see also Fig. 3, welded to the base plate ||,-`an'd has a hub 48 with laterally extending arms 49, '49. A circular wear plate 5I Vir'terpose'd between the pedestal 41 and the hub 48, and a -iianged retainer plate 52 bears against the hub 48V and is bolted to the pedestal `41 centrally rthereof to -hold theV swivel trame 44 in position for swiveling movement with respect to the base plate I A The reciprocating trough support 43 Amay be fabricated as a casting or formed by welding plate members together, and comprises a generally horizontal stepped support plate- 53 which isbent to provide a'support 54 for the Yinby 'trough section 42. The support plate is bent down to define a vertical wall 55 and -a further horizontal Vplateportion 56 extendingtoward the ou'tbyend of the trough section 42 and spaced therebelow The support plate 53 is stiffened by vertical -ankin'g rib's`151 depend'- ing therefrom. yA V-shaped guide rail r58 is sfecured to each outer side of the ribs 51 Aatfthe inby end thereof. N l A As seen in Fig. particularly, the swivel frame 44 is essentially T-shaped, and the extending arms 49, 49 thereof are each provided with 'a beveled roller 59 which rides the V-"sha'p'ed guide rail 56; The swivel frame 44' has a central tongue 6I having a clevis 612a-t lthe endth'e'reof whichV forms a support for a vroller 63; The inner sides of the flanking ribs 51 are engaged by the periphery of the roller 63, so that the rollers 59 land the Aroller 63 together guide the reciprocating trough-support 4-3 as it is swiveled about the base plate I I. j A

tA may be noted thaththe trough 4 2 maybe connected to other inby trough sections, not showin, Which may be supported'onvnon-reciprocating trough frame supports adapted to be `4 drawn back and forth across the working face by any convenient draft means such as is conventional with such devices, and in such a fashion that the reciprocating trough section 42, its reciprocating support frame 43, and the swivel frame 44 are swiveled with respect to the base I Means are provided for transmitting the reciprocating motion of the outby trough section 24 to the inby swivel trough section 42, and to this end the two sections are connected by a drive rod which functions to transmit such motion for all usual positions of angular displacement of the inby trough section 42. As shown particularly' with reference to Figs. 1 and 5, the two trough sections 42 and 24 are connected by a drive rod 64 .pivoted at one end to the frame 26 uihiderlying theoutby trough section 24 and to the other` end to the reciprocating trough support 43.

The reciprocating trough sup-'port 43 is additionally strengthened to take ythe forces induced by the drive rod 64 in transmitting the reciprocating movement of the outby shaker trough pan Y24 and to this end Ithe vertical wall 55 vand the horizontal plate portion 56 are stiffened by laterally disposed gusset plates 66 connected by a web 61 spaced above the horizontal plate portion 56. l

A pin 68, see also Fig. 2, extends through both the web 61 and `the horizontal plate portion `56 and forms a pivotal connection for the. drive rod 64 which is anchored below the web 161 and is provided with a ball and socket end 69:Y seen more particularly in Fig; 5, the p-in'IB is :held in position by a locking bar 1I screwed to an inturned army 12 of one of the gusset plates 66 and extending across a slot 13 in the pin 68.

The drive rod 64 is Vpivotally connected to the outby trough 24 by a headed pin 14 which passes thro-ugh the frame 26 and a clevis extension 16,' see Fig.' 4, extending from a transverse web :11 `of the Y-'shaped frame' 26,v the drive rod l64 hav ing a ball and socket I9 at the end .thereof similar to the ball and-socket 69.

It will be seen that the `ball land socket ends 469 and 18 of the drive rod 64 provide for a drivl' ing connection between the trough sections 52-4 and 42 in spite of irregularities in :the .mine floor upon which the trough connection Il) is located:

Itl will be noted from the description foregoing that the' drive rod 64' is located vunderneath the `inby trough pan 42 and the outby trough -pa'n 24 during all positions of swivelingof the frame 44. It will be seen that in extreme positions of swivel'-r -ing movement the reciprocating trough support A64 will be moved relative to its swivelmg 'iframe to accommodate the foreshortening by 'the 'pivotal movement of the drive rod 64': v"Suelo move'- :ment of the' inby trough section 24 is' infa direction towards the outby flared trough pan' 24'.-

Y It'l will also be seen .that the inby troughs'etio 42 is always in a position overlying the 'ared trough section 24 so that the contents of vthe? inby trough section 42` may discharge thereona't fall times, all rwithout the need'of articulated and nested troughing sections. By .the provision of the spring steel Vsides V'46' on `the outby trough section 24 vextremely wide Vangles' of .swiveling movement of the inby trough 42 may readily be accommodated.

The end portion-of the ared trough section 24 is surrounded by a relatively lowpupstanding wall |00 underlying the inby trough section 42 which facilitates retention of material being conveyed. As shownin Figi; onev ofthe-spring steel sides 46 lies alongside vthe corresponding side portion of wall |00, to form in effect a vertical continuation of the latter, whenever the inby trough section is turned out of engagement with the particular side 46.

While the invention has been shown and described in terms of a preferred embodiment thereof, the scope of the invention is intended to be limited only by the terms of the claims here appended.
